Battery recycling and solar infrastructure companies anchor a five-stock screen of green energy penny stocks, with CBAK Energy Technology (NASDAQ: CBAT) priced at $0.64 with a market cap of $56.73 million, and Aqua Metals Inc. (NASDAQ: AQMS) at $2.86 with a market cap of $9.62 million. The five names span lithium recycling, solar installation, EV charging, and grid services — sectors shaped by tightening carbon regulations and government procurement.
The Two Tickers With Live Price Data
CBAT and AQMS are the only names in the screen with current trading figures. CBAT sits within a 52-week range of $0.622 to $1.24, with 88.65 million shares outstanding and a float of 78.08 million. CBAK Energy Technology holds the distinction of being the first publicly listed Chinese lithium stock in the U.S. market energy sector; a distribution partnership with PowerOak, a portable power supply brand, adds a commercial channel to its manufacturing base.
AQMS carries a tighter float of 3.11 million shares and a 52-week range of $2.51 to $39.40 — a spread that reflects the volatility typical of micro-cap recycling names. Aqua Metals holds 68 patents for its AquaRefining technology, which recovers high-value metals from lithium-ion batteries. The company's commercial claim is that current recycling processes cannot recover lithium, while its AquaRefining process can, and it plans to produce both nickel and lithium hydroxide from recycled cells.
Battery Materials: ABML's Government Backing
American Battery Technology Company (OTCMKTS: ABML) has secured $4.5 million in government funding to expand battery materials production — the only disclosed dollar figure among the five companies in the screen. ABML's closed-loop process recovers materials from end-of-life batteries and purifies metals to the quality specifications required for re-entry into the manufacturing supply chain. Its extraction technology targets lithium from sedimentary claystone resources to produce battery cathode-grade lithium hydroxide.
Solar, EVs, and Grid Services
SPI Energy Co. (NASDAQ: SPI) operates across photovoltaic markets in China, Japan, Europe, and North America, generating revenue from EV manufacturing, EV charging solutions, and engineering and construction services to independent power developers. Orbital Infrastructure Group (NASDAQ: OIG) provides engineering, design, construction, and maintenance services to electric power, telecommunications, and renewables sectors; the company is currently evaluating strategic alternatives to improve growth prospects.
Structural Risks in the Penny Tier
Three of the five tickers — ABML, SPI, and OIG — show no current price or market cap data, a routine condition for stocks on OTC exchanges that carry no SEC filing requirement. Low liquidity, infrequent trading, and the absence of minimum listing standards are the primary structural risks across this category. Thin volume also raises the risk of price manipulation and makes exiting positions difficult, regardless of the underlying business case.
